In some instances, it may be desirable to provide a side-to-side anastomosis between two naturally occurring lumens within a patient's body. By way of example only, it may be desirable to provide an anastomosis between two portions of a patient's gastrointestinal tract, such as between the patient's duodenum and the patient's ileum. In some patients, it may improve glucose control, serve as a treatment for type 2 diabetes, and/or provide other results when the jejunum is diverted by an anastomosis. In such a procedure, a first enterotomy may be formed in the sidewall of the duodenum while a second enterotomy is formed in the sidewall of the ileum. The sidewalls may then be positioned adjacent to each other to form an anastomosis between the portions of the duodenum and the ileum in which the enterotomies are formed, as described in greater detail below. The anastomosis establishes direct fluid communication between the adjacent portions of the duodenum and ileum, enabling at least some nutrient-rich chyme to pass through the anastomosis to travel from the duodenum directly to the ileum without passing through the jejunum. In other variations in which the anastomosis is positioned at other locations within the gastrointestinal tract, some chyme may pass through a shortened portion of the jejunum. In either case, the anastomosis enables accelerated passage of nutrient-rich chyme through the gastrointestinal tract.
One or more devices may be positioned within the first and second enterotomies to hold the sidewalls of the duodenum and ileum together, thereby holding the first and second openings in alignment with each other and maintaining patency through the openings. The device or devices may compress the tissue, which may ultimately result in a serosa-to-serosa adhesion that secures the duodenum sidewall to the ileum sidewall. In addition, tissue captured in the device or devices may eventually necrose, such that the device or devices is/are eventually released into the gastrointestinal tract and subsequently passed through the bowels. Traditional examples of anastomosis devices include Denan's rings and the Murphy button. Examples of anastomosis procedures and associated devices are taught in U.S. Provisional Patent App. No. 61/697,845, entitled “Magnetic Compression Anastomosis Device,” filed Sep. 7, 2012, the disclosure of which is incorporated by reference herein; U.S. Pat. No. 9,364,238, entitled “Method and Apparatus for Joining Hollow Organ Sections in Anastomosis,” issued Jun. 14, 2016, the disclosure of which is incorporated by reference herein; and U.S. patent application Ser. No. 15/298,816, entitled “Method for Partial Diversion of the Intestinal Tract,” filed Oct. 20, 2016, the disclosure of which is incorporated by reference herein.
While a variety of anastomosis devices and methods have been made and used, it is believed that no one prior to the inventor(s) has made or used an invention as described herein.
While the specification concludes with claims which particularly point out and distinctly claim the invention, it is believed the present invention will be better understood from the following description of certain examples taken in conjunction with the accompanying drawings, in which like reference numerals identify the same elements, and in which:
The drawings are not intended to be limiting in any way, and it is contemplated that various embodiments of the invention may be carried out in a variety of other ways, including those not necessarily depicted in the drawings. The accompanying drawings incorporated in and forming a part of the specification illustrate several aspects of the present invention, and together with the description serve to explain the principles of the invention; it being understood, however, that this invention is not limited to the precise arrangements shown.
The following description of certain examples of the invention should not be used to limit the scope of the present invention. Other examples, features, aspects, embodiments, and advantages of the invention will become apparent to those skilled in the art from the following description, which is by way of illustration, one of the best modes contemplated for carrying out the invention. As will be realized, the invention is capable of other different and obvious aspects, all without departing from the invention. Accordingly, the drawings and descriptions should be regarded as illustrative in nature and not restrictive.
As noted above, it may be desirable to provide an anastomosis between two anatomical structures within a patient's body, such as two portions of a patient's gastrointestinal tract.
The gastrointestinal tract (2) is shown including an exemplary anastomosis (18) formed between a proximal portion of the jejunum (10) and the ileum (12). The anastomosis (18) has an inlet side formed through a sidewall of the jejunum (10) at a location adjacent to and downstream of the duodenojejunal flexure (16) and the ligament of Treitz (14). The anastomosis (18) additionally has an outlet side formed through a sidewall of the ileum (12). It will be appreciated that the anastomosis (18) may be positioned at various other suitable locations along the gastrointestinal tract (2). For example, as shown in
Still referring to
Forming a side-by-side anastomosis (18) between two portions of the gastrointestinal tract (2), positioned adjacent to one another, may be achieved using a compression device having first and second device portions that clamp intestinal tissue therebetween, as described above. In some procedures, the device portions may be introduced into the intestinal lumen via two or more enterotomies formed in the intestinal sidewalls at respective upstream and downstream locations. In other procedures, the device portions may be introduced into the intestinal lumen endoscopically, using two or more endoscopes inserted through naturally occurring body orifices and directed into the intestinal lumen from opposing directions. The exemplary tissue compression devices disclosed herein may be positioned within a patient using either of these methods, for example.
As will be described in greater detail below, the first and second device portions of the tissue compression devices disclosed herein may include magnetic members that draw the device portions together. The device portions, when drawn together magnetically, compress tissue positioned therebetween with a clamping force sufficient to cause ischemia and eventual necrosis of the tissue. Once necrosis occurs, the device falls away to reveal an anastomosis, and the device is then passed downstream through the gastrointestinal tract (2).
It should be understood that it may be desirable to provide contoured edges in a tissue compression device that is used to form an anastomosis. Such contoured edges may provide better tissue shaping than the tissue shaping that would otherwise be provided by sharp edges. Moreover, smooth mating surfaces in a tissue compression device may reduce the likelihood that tissue captured between the surfaces will interfere with the mating of such surfaces. Several exemplary configurations that provide contoured edges and smooth mating surfaces are described in greater detail below.
A. Structural Features of Exemplary Tissue Compression Device Having Contoured Mating Surfaces
As best shown in
As best shown in
The first and second mating surfaces (38, 40) are shaped with complementary contours that facilitate alignment of the device halves (22, 24) with one another, and enable the device halves (22, 24) to mate together in contacting engagement along the full length of the mating surfaces (38, 40). As shown best in

As seen by a comparison of
As described above, the first mating surface (38) includes concave contours and the second mating surface (40) includes complementary convex contours. In alternative versions, the mating surfaces (38, 40) may be provided with various other arrangements of concave and convex contours suitable to facilitate alignment of the first and second device halves (22, 24) with one another during use, while maintaining adequate compression of tissue positioned therebetween. For example, the first mating surface (38) may include one or more concave portions and/or one or more convex portions, and the second mating surface (40) may include a complementary arrangement of one or more convex portions and/or one or more concave portions. The concave portions and/or convex portions may be separated by one or more planar portions as desired. Further, a first set of one or more mating pairs of the contoured portions may be shaped with a first radius of curvature, while a second set of one or more mating pairs of the contoured portions may be shaped with a second radius of curvature. As described above, the first and second radii of curvature may be defined within respective first and second planes that are orthogonal to one another.

Each magnetic member (62) is generally disc-like or cylindrical in shape in the present example, and is fixed at an inner end of its respective socket (64), such as by bond or press fit, for example. Alternatively, the magnetic members (62) may be threadedly engaged with their sockets (64), or one or more of the magnetic members (62) may be slidable within its socket (64) and provided with a latching feature. Such latching feature may be configured to lockingly engage an opposing magnetic member (62) of the other device half (22, 24), for example as disclosed in U.S. patent application Ser. No. 15/419,086, entitled “Magnetic Tissue Compression Device with Backup Mechanical Latch,” filed on Jan. 30, 2017, issued as U.S. Pat. No. 10,206,682 on Feb. 19, 2019, the disclosure of which is hereby incorporated by reference herein.
In the present example, each magnetic member (62) is in the form of, or otherwise include, a permanent magnet provided with a magnetic polarity opposite that of the opposing magnetic member (62) carried by the other device half (22, 24). In some versions, the magnetic members (62) of each device half (22, 24) may be provided with opposite polarities. In other embodiments, the magnetic members (62) of the first device half (22) may have a first polarity, while the magnetic members (62) of the second device half (24) may an opposite second polarity. In either case, the magnetic members (62) of each device half (22, 24) are configured to magnetically attract the magnetic members (62) of the other device half (22, 24). Accordingly, the device halves (22, 24) are configured to magnetically draw together and compress tissue positioned therebetween to form an anastomosis, as described in greater detail below.
While the magnetic members (62) are shown in the form of permanent magnets, in alternative versions they may be in the form of electromagnets, for example. In other versions, the magnetic members (62) may include a combination of one or more permanent magnets and one or more electromagnets. In that regard, the tissue compression device (20) may further include a circuit assembly having one or more electromagnets and/or one or more illumination devices or other suitable electrical elements, for example as generally disclosed in U.S. patent application Ser. No. 15/419,102, entitled “Battery Powered Electromagnetic Tissue Compression Device,” filed on Jan. 30, 2017, published as U.S. Pub. No. 2018/0214151 on Aug. 2, 2018, the disclosure of which is hereby incorporated by reference herein.

The tissue compression device (20) may further include various additional features not shown herein, such as one or more mechanical latching mechanisms, compressible members, and/or suture bores as disclosed in U.S. patent application Ser. No. 15/419,086, issued as U.S. Pat. No. 10,206,682 on Feb. 19, 2019, incorporated by reference above. Such suture bores may be used in combination with suture materials and methods as generally disclosed in U.S. patent application Ser. No. 15/419,151, published as U.S. Pub. No. 2018/0214152 on Aug. 2, 2018, entitled “Tissue Compression Device with Features to Contain Needles and Suture During Packaging and Placement in Body,” filed on even date herewith, the disclosure of which is hereby incorporated by reference herein.
B. Exemplary Procedures for Forming an Anastomosis Using Exemplary Tissue Compression Device Having Contoured Mating Surfaces
Referring to
An exemplary instrument (94) is used to facilitate deployment of the device halves (22, 24) within a patient. As shown in
To load the device half (24) onto the instrument (94), as shown in
As shown in
In alternative versions, rather than using instrument (94) as described above, each device half (22, 24) may be deployed by grasping its bridges (74) with any suitable grasping instrument (not shown). For example, the grasping instrument may be manipulated to grasp the notched trailing edges (78) of the bridges (74) of a particular device half (22, 24), and further manipulated to suitably position the device half (22, 24) within an enterotomy (90, 92) such that the resilient clips (80) engage the surrounding tissue. Advantageously, the openings (72) formed in the outer periphery (32, 36) of each device half (22, 24) may enable grasping elements of the grasping instrument to project through the device half (22, 24), from the open mating side, to thereby achieve a secure grip of the bridges (74) and maximize manipulation control of the device half (22, 24) during placement. The openings (72) may also serve to provide access to the bridges (74) through the outer peripheries (32, 66) of the device halves (22, 24). Accordingly, the openings (72) enable engagement of the bridges (74) with a grasping instrument after the device halves (22, 24) have magnetically coupled together (see

Compression of the tissue sidewalls (8, 12) between the mating surfaces (38, 40) induces serosa-to-serosa adhesion between the sidewalls (8, 12) at a perimeter surrounding the device (20). Additionally, the compressive clamping force exerted by the mating surfaces (38, 40) is sufficient to cause ischemia and eventual necrosis in the clamped tissue. With passage of time, such as approximately four days to two weeks, for example, the compressed tissue fully necroses and detaches from the surrounding healthy tissue (8, 12), now bonded together via serosa-to-serosa adhesion. Advantageously, the smooth outer periphery and low-profile, pill-shaped configuration of the device (20) minimizes interference of fluid flow through the duodenum (8) and ileum (12) during the necrosis period.

C. Exemplary Alternative Anastomosis Tissue Compression Device Having Mating Internal Compression Members
Similar to tissue compression device (20) described above, tissue compression device (120) is formed with a length that is greater than its width so as to present an elongate, low-profile, pill-shaped structure. Additionally, device (120) is formed with a transverse cross-section having a rounded shape to provide the device (120) with a rounded and smooth outer periphery. As shown in
